you have no empirical data and I do.

What does your empirical data say about the amount of energy reflected to space by the bare desert as compared to the amount reflected by the solar panel?

 

[ding]

It must be a lot of cooling, right?
If it's going to trigger an ice age.

That depends on how much solar radiation they convert to electricity. It only takes a reduction of 0.7 W/m^2 to change from net warming to net cooling

It doesn’t. It only measured the incremental cooling effect due to converting solar radiation into electricity at six solar farms.

That depends on how much solar radiation they convert to electricity.

Don't forget the much lower albedo of the panel.

If you only look at part of the system, your math will always be wrong.

It only takes a reduction of 0.7 W/m^2 to change from net warming to net cooling

How many W/m^2 are absorbed by bare desert? How many W/m^2 are absorbed by the panel?

 

[Toddsterpatriot]

It doesn’t. It only measured the incremental cooling effect due to converting solar radiation into electricity at six solar farms.

You ignored albedo? No wonder why your silly claims are so wrong.
Not to mention your confusion about the FLoT.

Post your empirical data and let’s find out.

Post your empirical data and let’s find out.

At sea level, the Earth receives about 1000 W/meter^2
Solar panels will absorb about 95% of that, the desert sand, about 60%.

Now your magic FLoT violating electicity generation/usage has to somehow
get at least 350 W/m^2 back into space (or storage) without heating the surface or atmosphere,
before we can even start to think about cooling, rather than heating the planet.

Darn it, even some of the studies noticed that lower albedo results in higher temperatures
over the panels.

"Solar panels forest" and its radiative forcing effect: preliminary results from the Arava Desert

The production of electricity from solar radiation should replace power production by burning fossil fuel and help reduce atmospheric concentrations of CO2. However, large photovoltaic (PV) fields can also influence the climate in more direct ways. The albedo of solar panels is low to allow...

200W/m^2 of EXTRA heating.

The albedo of solar panels is low to allow efficient light absorption, but actual conversion efficiency is below 20%. The remaining 80% of the energy is reflected, re-emitted as thermal radiation or dissipated as sensible heat (H). These effects can heat the surface, influence local air circulations, and lead to the formation of "heat-islands". Such effects are particularly significant in desert areas with high radiation load and high background albedo.

Don't you hate that?

Post your empirical data that electricity usage heats the surface of the planet like solar radiation.

FLoT says the energy converted into electricity isn't destroyed.

Now post your empirical data that shows the extra 35% of the sunlight absorbed
by the solar panels, as compared to the desert soil, doesn't heat the planet.

Did the data really show that it was cooler because the electricity was generated?

I only needed to show the empirical data for how converting solar radiation into electricity created an incremental cooling effect at solar 6 solar farms. It’s your responsibility to produce the empirical data that shows how electricity usage warms the surface of the planet like solar radiation does.

So that's a no.

That’s a present your empirical data showing electricity usage warms the surface of the planet like solar radiation does.

The real test of your claim would be to measure the temperature while the
array is sending out power and then again after the plug was "pulled".

And in either case, as the Israeli study showed, there is still
a heat island effect due to the much lower albedo of the panels.

That’s nice. I think you are an idiot for believing electricity usage heats the surface of the planet like solar radiation does.

Show me how the heat from the electricity is different than that from the sunlight.

I already have. Many times.
